Hg-Mn star, SB2
Parameters of the primary A: Teff=10750K, logg=3.60; vturb=0.0 km/s, vsini=0.0 km/s
Parameters of the secondary B: Teff=8500K, logg=4.00; vturb=0.0 km/s, vsini=8.0 km/s
L(A)/Ltot=75%
L(B)/Ltot=25%
All the above parameters were adjusted to fit the line spectrum.
The spectrum of the B star can be seen blueward of the spectrum of the A star.
lambda(B)-lambda(A)=-0.16 A at 3933 A (DVd=-12.5 km/s)
